There’s still great single player games getting made. But the sad fact is that they don’t make anywhere near as much money as “live service” type games. Traditional single player games rely solely on the initial sales to make money. Live games like Destiny or The Division and multiplayer games like Overwatch, Fortnite, CoD etc. have a constant revenue stream via micro transactions that end up making huge profits years after initial release. That why traditional single player games are trying to adopt certain aspects of these models. Games like GTA V, Shadow of War, Assassins Creed, Far Cry would once of been straight forward play and put down single player experiences. Now they’ve got micro transactions, live events, timed DLC’s etc. They are trying get a piece of the “live game” pie. Meanwhile traditional single player games like Wolfenstein or Prey get good reviews but are generally considered financial disappointments because they don’t achieve the large sales targets required to justify not having micro transactions. God of War is a bit different because it’s a Sony backed console exclusive. It’s main purpose is to sell consoles not sell games. Sony can afford to risk a financial loss on that game if it sells a lot of consoles as a result. They obviously put a lot more time and money into that game than other publishers would normally put into a game. Because it’s tent pole game. You can bet your ass that if it wasn’t being backed by Sony it would have micro transactions as well.
